*You can use whatever kind of pasta you want: whole wheat, gluten free, low carb, whatever you want! I use the pasta from Great Low Carb Bread Company. It's fabulous considering how low carb it is.
**You have a lot of leeway when it comes to cheese. I opted for gruyere because I was feeling fancy, but cheddar is perfect for that classic mac n cheese taste. You can also use vegan cheese, but I have a vegan-friendly recipe mac n cheese recipe in the works... stay tuned. In terms of cheese measurements, ¼ cup shredded cheese is equal to an ounce. I gave you the option for 1 or 2 ounces depending on how much of a cheese fiend you are, plus you can save the calories/fat of a second second ounce. Up to you!
***You can use whatever milk you want. Obviously half and half will be creamier than milk, but is significantly higher in fat. You also may want a lighter sauce, so you can use a lower fat milk or even almond milk. Yay for options.
